What to do on a Sunday in London?

So, I woke up this morning in and it was raining – again! Then I thought, hey, London is actually not a bad place to live… Whatever the weather there’s always something to do. Today I might go check out Dr Gunther von Hagen’s Body Worlds exhibition at the O2 (something I’ve been talking about forever but never seem to find the time to do!) – that’s after I’ve bought myself that new pair of trainers I’ve been promising myself for a while. And tonight, after having had some near-enough authentic Mexican food at Westbourne Grove’s Taqueria, I might convince my girlfriend that tonight’s the night to see the new T4 – all in all a satisfying and well spent Sunday in London; I’m sure a few of you North Americans out there will agree!
